The problem is that you are trying to run the command "who am i" (with
spaces), if you try that on the commandline you should get the same
error.
$ "who am i"
Just remove the quotes:
my $usr = qx(who am i);
And it should work.
But..., as allways with perl, TIMTOWTDI. You can get the user id
without having to run external programs. See the variables $< and $>
in 'perldoc perlvar', and if you need the username, not just the
numeric user-id just use getpwuid to look it up.
my $user = getpwuid $<;
